Product details
Overview
R5F21366CNFP#30 from Renesas Electronics is a 16-bit R8C CPU core microcontroller with 32 KB program ROM, 2.5 KB data flash (4 × 1 KB blocks), and 2.5 KB RAM in a 64-pin LQFP (PLQP0064KB-A) package. It operates at up to 20 MHz (VCC = 2.7–5.5 V), features hardware LIN support via Timer RA and UART0, and integrates 12-channel 10-bit ADC, dual 8-bit DACs, and six independent timer modules - enabling real-time motor control and appliance system management.
For engineers reviewing the R5F21366CNFP#30 datasheet, R5F21366CNFP#30 pinout, R5F21366CNFP#30 application, or R5F21366CNFP#30 equivalent, key selection considerations include its background operation (BGO) data flash capability, −20°C to +85°C industrial temperature grade (N version), integrated voltage detection circuitry, and support for low-power wait/stop modes down to 2.0 µA.
Technical Context
The R5F21366CNFP#30 implements the R8C CPU core with 89 fundamental instructions, 1 Mbyte address space, and a dedicated 16×16→32-bit multiplier with multiply-accumulate capability. Its clock system includes four independent sources: XIN oscillator (up to 20 MHz), XCIN 32 kHz crystal input, high-speed on-chip oscillator (frequency-adjustable), and low-speed on-chip oscillator - all selectable via software-controlled dividers (1/2/4/8/16).
Peripheral integration centers on deterministic real-time control: Timer RD provides complementary PWM for three-phase motor drive (6-pin output, triangular/sawtooth modulation), Timer RC supports programmable waveform generation, and the LIN module uses UART0 with Timer RA for hardware-level protocol handling without CPU intervention.
